Assassination Photo

FILE - In this Monday, Dec. 19, 2016 file photo, Mevlut Mert Altintas shouts after shooting Andrei Karlov, right, the Russian ambassador to Turkey, at an art gallery in Ankara, Turkey. At first, AP photographer Burhan Ozbilici thought it was a theatrical stunt when a man in a dark suit and tie pulled out a gun during the photography exhibition. The man then opened fire, killing Karlov. (AP Photo/Burhan Ozbilici) ORG XMIT: NY787
